1 Claim.

Air hose, as usually found at filling stations, is mounted on a reel andconnected with an air supply through the reel. The reel as ordinarilyarranged is spring wound so that the air hose is withdrawn whenreleased. The present invention is designed to provide a protectingdevice for the operating or free end of the hose, affording a bettergrip for the end of the hose, preventing kinking of that end of the hoseand forms a stop for the hose as it is returned by the reel, andprovides a protection for the chuck or valve at the end of the hose whendropped to the pavement. Features and details of the invention willappear from the specification and claim.

A preferred embodiment of the invention is illustrated in theaccompanying drawing as follows:

Fig. 1 shows a perspective view of the hose in the ordinary set up andin position of use.

Fig. 2 a longitudinal section of the protector in 30 place on a hose.

Fig. 3 a section on the line 3-3 in Fig. 2.

Fig. 4 a sectional view showing the outline and general arrangement ofthe reel.

I marks the hose. This is provided with a valve :5 or chuck 2 atits'free end. This chuck is secured to the hose by a clamping ring 3.The valve has a small shoulder 4 at its union with the hose. Aprotecting tube 5 of rubber has an inside diameter approximating that ofthe air hose I. to This is reinforced by a coil spring 6 which ispreferably embedded in the rubber as it is vulcanized. This coil spring,while permitting a certain freedom or flexibility of the hose at theend, does prevent kinking of the hose when it is 5 pulled at an angle.The outer surface of the protecting tube has annular ribs 1. Thesepreferably extend directly around the wall and do not follow the line ofthe coil spring. The protecting tube terminates at its rear end in anenlargement 8, preferably in the form of a ball which is designed toform a stop for the hose as it is withdrawn by the reel. An ordinaryreel is shown in perspective in Fig. 1 and in section in Fig. 4. In Fig.4 a spring locked reel 9 is indicated. This is mounted in the reel caseIll having the roller guarded opening it forthe hose. The ball 8 engagesthe wall of the opening I! so as to limit the return movement of thehose. 10

In Fig. 1 the hose is shown in use. An automobile tire l2 has a tirevalve I3 and this is engaged by the chuck or valve 2 in the fillingoperation in the usual manner.

In drawing the air tube to position to engage the tire valve the end ofthe tube is swung so as to make the proper engagement and this ofteninvolves a comparatively short bend at the free end of theair tube. Theprotector while permitting some flexibility in this respect so as toprevent localizing of the bend prevents kinking as this is pulled. Thegripping surface gives a very much better hold on the air tube. If theair tube is dropped the rubber tube holds the valve or check 2 01f thepavement and the enlargement 8 makes a cushion stop for the hose when itreaches the opening.

What I claim as new is: e

A hose grip and protector comprising a rubber tube adapted to fit overand engage the walls of the hose to be gripped and protected, said tubehaving an integral rubber enlargement at one end forming a reel stop,the enlargement being of greater diameter than the balance of the tubeand the body of said tube being formed of resilient rubber throughout.JOSEPH H.
